Description
This circuit consists of two independent, high gain, internally frequency compensated operational amplifiers, designed specifically for automotive and industrial control system. It operates from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, these circuits can be directly supplied from standard +5 V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply. In linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply.
